Ok, so coming from a GSR I must ask, is the SRT-4 as safe as they say it is? I mean, I had all the bells and wistles installed for the GSR and still got stolen.

Also, say a thief steals an SRT, what good does it do him? I mean, if he has no original key with the code in the key, he can't go to the dealer/friend at the dealer and say give me a copy of this key...or can he?

I'm asking this as part of my research on the reliability of the SRT. I'm almost done researching the SRT and so far so good. I would never have thought I'd be buying an American car but it seems the SRT will be my next car. I just sold my VW GTI Vr6 MK3.

So, if the SRT is stolen, what use does the thief have besides parts? :readclose

Search, titles only, "stolen" in the Canadian section. Since those poor buggers have had the most SRTs stolen (all flatbedded, BTW, it's that good) the most discussion and analysis of the system has taken place in those threads.

I see.

So you're saying there is absolutely NO way to get a copy of a key if you can prove ownership and what not? What happens to the people that lose their keys? Are they out of luck because they can't have a key like the original? I'm confused.

I make copies of these keys for $5 all day long....

LOL, nah you would have to prove ownership of the car before getting a copy of the key...

but there are ways around the sentry system I hapen to know about. So if your car thief happens to know some shit about computers, he may not need the original

I don't mean copying the original. Say the original was lost and you are the owner of the car and you can prove that you are the owner of the car by having registration insurance, ID, payments, etc... THEN would the dealer make a new key for THAT car with out the original? It seems this key is too secure for it's own good, lol.

Oh im sure, if you prove you are the owner of the car, the dealership would get you another key. Probably for a hefty price but it would have to happen

Well the technology they use in our keys is the same technology they use for Speedpasses at gas stations.

There is a way to do it....but it would require you to have possesion of the original key so you could copy it....

I will try to dig up the article, but its been posted up here before

SENTRY KEY IMMOBILIZER SYSTEM
The Sentry Key Immobilizer System (SKIS) is
available as a factory-installed option on this vehicle.
It is designed to provide passive protection against
unauthorized vehicle use by disabling the engine,
after two (2) seconds of running, whenever an invalid
key is used to start the vehicle. The SKIS is active
whenever the ignition is on and does not require any
customer intervention. The primary components of
the system are the Sentry Key Immobilizer Module
(SKIM), Sentry Key (ignition key with a transponder
molded into the head), indicator light, and the Powertrain
Control Module (PCM). The SKIM is mounted
to the steering column with the molded, integral
antenna mounted on the trim ring surrounding the
ignition lock cylinder. The indicator light, is located
in the instrument cluster.
SENTRY KEY IMMOBILIZER SYSTEM
The SKIS includes keys from the factory which are
pre-programmed. Each SKIM will recognize a maximum
of eight Sentry Keys. If the customer would
like to own additional keys other than those provided
with the vehicle, they can be purchased from any
authorized dealer. These keys must be programmed
to the SKIM on the vehicle in order for the system to
recognize them as valid keys. This can be done by
the dealer with a DRB IIIt scan tool or by a customer
if this feature is available in their market and
they have two (2) valid keys already available to
them.
DESCRIPTION
The Sentry Key Immobilizer System (SKIS) uses a
transponder chip that is integral to each ignition key
(Fig. 3) to communicate with the Sentry Key Immobilizer
Module (SKIM). Ignition keys are supplied
with the vehicle when it is shipped from the factory.
The transponder chip is undermolded within the
head of the key. This undermold is hidden beneath
an overmolded rubber cap.
OPERATION
Each Sentry Key transponder has a unique transponder
identification code programmed into it by the
manufacturer. The Sentry Key Immobilizer Module
(SKIM) has a unique “Secret Key” code programmed
into it by the manufacturer. When a Sentry Key
transponder is programmed into the memory of the
SKIM, the SKIM learns the transponder identification
code from the transponder, and the transponder
learns the “Secret Key” code from the SKIM. Each of
these codes is stored within the transponder and in
the nonvolatile memory of the SKIM. Therefore,
blank keys for the SKIS must be programmed by and
into the SKIM, in addition to being cut to match the
mechanical coding of the ignition lock cylinder.
The Sentry Key’s transponder is within the range
of the SKIM’s transceiver antenna ring when it is
inserted into the ignition lock cylinder. When the
ignition switch is turned to the ON position, the
SKIM communicates with the Sentry Key via a radio
frequency (RF) signal. The SKIM determines if a
valid key is present based on the information it
receives from the Sentry Key. If a valid key is
detected, that fact is communicated to the PCM via
the PCI bus and the vehicle is allowed to continue
running. If an invalid key is received by the PCM or
no status at all is communicated, the vehicle will
stall after two (2) seconds of running. The indicator
light will be flashing at this point. The Sentry Key’s
transponder can not be repaired. If it is faulty or
damaged, it must be replaced.

See? Hope that clears everything up for you.

Yep, only took a university team a few months, like 60lbs of computers in the back seat, and a bunch of keys from TI, the makers of the system. Oh, and they had to be within a few inches of your key to clone it:) I know all about that. They say it can be reproduced and downsized. But that time is not yet. Until some shows me a car actually stolen this way, it's still just an experiment. Sucessful, but not a threat to any car yet.

It's about possible vs probable.

Noted....but it says they don't need any keys. Wonder how they do THAT trick without a DRB?
Any-hoo, only works on Pacificas, or so they claim.
